Almost always at kickoff, but whose kickoff depends on a setting your commissioner chose in August. Below: how to tell which setting your league runs, what to do about a player who is already locked, and the count nobody mentions, which is how many separate deadlines one NFL week actually hands you. DraftIcon locks players the same way, for the same reason, and the difference is only what missing one costs you.
In most leagues each player locks at his own kickoff, so a Thursday night starter is frozen while everybody else stays editable until Sunday. If your whole roster went grey on Thursday, your league uses the other setting, where the first game of the week locks everyone at once.
Once a player is locked he cannot be moved between your starters and your bench, and in most leagues he cannot be dropped or traded either. Nothing unlocks him. He counts wherever he was sitting when his game began.
Four reasons cover nearly every case. Find yours, and the line underneath tells you what is still possible.
The ordinary one. Each player freezes at about his own listed kickoff time, so a Thursday night receiver is untouchable while your Sunday players are still free.
Nothing to do. He scores where he sat.Some leagues freeze all roster moves at the first game of the week, even when that game is on Thursday. If everybody greyed out together, this is why.
Set the whole lineup before Thursday night.A player with no game does not have a kickoff of his own, so leagues treat him differently. Many lock him once the week's first game begins, which surprises people every October.
Bench him early in the week, not on Sunday.A player who has just been dropped, or who is sitting inside a trade waiting for approval, is held in place until that process finishes.
Wait for the claim or the trade to clear.There is one thing that is not on this list, because it does not exist: an undo. No platform lets you move a player after his game has started, and no commissioner tool restores a lineup you meant to change. If the points already happened, they belong to whoever was in the slot.
Every big platform offers roughly the same choice, under slightly different names. Your commissioner picked one in August and probably never mentioned it.
To find yours, open the league settings and look for lock time or roster lock. The exact wording lives in each platform's own help pages, and the ESPN support site is the most detailed of them if your league runs there. Everything on this page was read from those official help pages on 10 September 2026.
Under the ordinary setting, a lineup does not have a deadline. It has a series of them, spread across four days, and each one takes a decision away from you at a different hour. A regular week, in Eastern time:
None of this is a flaw in the platforms. It is what happens when a weekly game is bolted onto a schedule built for television. But it is the honest reason people search for lock times at midnight on a Wednesday, and it is why how much time fantasy football takes is a question with an uncomfortable answer.
This is our own game, so weigh it accordingly, and the first thing to say is that we have the same lock. DraftIcon freezes a card the moment that player’s game kicks off, and from then on he cannot be traded out of your team. We could not do it any other way, for the reason set out further down.
Three things are different, and they are the ones that matter on a Sunday morning. Trading during the week is optional here rather than compulsory: the ten cards you drafted are already a complete team, so a week where you never reopen the app is a normal week rather than a forfeited one. A player on a bye cannot end up in your team at all, because players without a game that week are not in the pool you draft from. And no setting exists that freezes everything at the first kickoff, so Thursday night never takes your Sunday with it.
What is left is the weight of the mistake. Miss a lock in a season league and it follows you through the standings for four months. Miss one here and the week ends on Monday, and Friday deals a new pack.
Cards come out of a pack, the clock runs on every pick, ten of them make a team. Trade during the week if you feel like it, or leave it exactly as drafted.

The ten cards you drafted are already a finished team. You can trade a player out while his game has not started, and you can equally close the app on Friday and let the weekend happen.
The lock exists for a good reason, and it is worth saying so. Without it, anybody could watch a running back leave the field injured and swap him out retroactively, and the whole competition would collapse into whoever refreshed fastest. Every fantasy game needs a moment after which the decision stands, ours included.
That is why our rule is the same one, player by player, at kickoff. What we changed is not the rule but the weight resting on it. In a season league a missed lock sits in the standings until December, so the deadline has to be tracked. Here the week is the entire competition, so the worst case is one Sunday.
What a season league gives back is the roster you built and defended for months, and a lineup call that genuinely is a skill. If that is what you want, keep it. The time it takes sets out the weekly cost honestly, and weekly redraft explains the format that removes it.
In most leagues each player locks at about his own kickoff, so your roster closes in stages across Thursday, Sunday and Monday. Leagues can instead be set so that every move locks at the first game of the week.
Because his game has already started and theirs have not. Under the individual kickoff setting a Thursday night player is frozen from Thursday, while a player in the four o'clock window stays editable most of Sunday.
Your league locks the whole roster at the first game of the week rather than player by player. Once that opening kickoff passes, nothing can be moved until the week ends.
Under the usual setting, yes, for everyone whose game has not started. Under the first-game setting, no. Check the lock time entry in your league settings, because the two behave completely differently.
Generally not. Most leagues hold a player in place from his kickoff, so he cannot be moved between slots, dropped or included in a trade until the week is over.
Commissioner tools can correct a roster in some situations, but no platform lets points already scored be reassigned to a different slot. Treat the lock as final and ask before the game rather than after it.
He has no kickoff of his own, so leagues commonly lock him once the week's first game starts. That is why a bye week player left in your starters on Saturday often cannot be moved on Sunday.
Under the individual kickoff setting, as many as there are kickoff windows: Thursday night, the international morning game, one o'clock, both four o'clock windows, Sunday night and Monday night.
DraftIcon has the same kickoff lock, but the week is the whole competition. The ten cards you draft are already a complete team, trading during the week is optional, and anything you get wrong is finished on Monday instead of following you into a table until December.
